摘要

水性锌离子电池(zib)受到了广泛的关注。由于锌阳极的严重腐蚀和枝晶的生长,阻碍了ZIBs的进一步应用。本文在Zn表面引入了由海藻酸锌凝胶(Alg-Zn)和酸化导电炭黑(AB)组成的人工混合电子离子导电涂层(Alg-Zn + AB@Zn)。制备的混合涂层不仅提供了更多的Zn成核位点,而且有效地降低了Zn的成核过电位。因此,Alg-Zn + AB@Zn对称电池可以稳定地保持极低的电压滞后。此外,Alg-Zn + AB@Zn赋予Zn/AC全电池优异的循环稳定性,特别是在高电流密度下。近100%的容量保留率可以在10?在10g下循环000次?1和16?在20g下,000次循环?1,据作者所知,在高电流密度下,优于其他报道的Zn/AC全电池。

High cycle stability of Zn anodes boosted by an artificial electronic–ionic mixed conductor coating layer†

Aqueous zinc ion batteries (ZIBs) have received widespread attention. Due to serious corrosion of Zn anodes and dendrite growth, further application of ZIBs is hindered. Herein, an artificial mixed electronic–ionic conductive coating layer (Alg-Zn + AB@Zn) consisting of zinc alginate gel (Alg-Zn) and acidified conductive carbon black (AB) is introduced on the surface of Zn. The as-prepared mixed coating not only provides more Zn nucleation sites, but also effectively reduces the nucleation overpotential of Zn. Therefore, the Alg-Zn + AB@Zn symmetrical cell can stably maintain an extremely low voltage hysteresis. Furthermore, Alg-Zn + AB@Zn endows the Zn/AC full cell with excellent cycle stability, especially at high current densities. A capacity retention rate of nearly 100% can be achieved over 10?000 cycles at 10 A g?1, and 16?000 cycles at 20 A g?1, superior to those of the other reported Zn/AC full cells at high current densities, to the best of the authors' knowledge.
